The present improvements, relating as indicated to a vehicle wheel rim,have more particular regard to so-called Q. D or quick detachable rimsfor pneumatic tires, such as are largely usen in connection withautomobiles. rlhis trade-name Vis somewhat of a misnomer, for the rimitself is not actually detachable at all, but merely has a side flangewhich may be detached in order to facilitate the placing; on andremoval'of a tire from lthe rim1 The object of the present invention isto provide improved lockingmeans for securing such detachable sideflange in place on the rim., and to the accomplishment of suchobject theinvention., then, consists of 'the means hereinafter fully described andparticularly pointed outin the claims.

The annexed drawing and the following description set forthin detailcertain mechanism Vembodyingl the invention, such disclosed'meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

- in said annexed drawing:-

Figure l is a side elevational view of the so-called quick detachablerim Vshowing my improved locking` device incorporated therein; Fig. 2 isa view similar to Fig. l but showing the locking device in inoperative lposition; Fig. 3 is a transverse section of the same taken on the planeindicated hy the line 3 3, Fig. l; and Fig. fl is a section of a detailtaken on a plane parallel with the plane of the wheel, as indicated bythe line efr-4,5m. 3. Y

The construction of the wheel body, of which a portion of the telly lonly is shown in the aforesaid drawing, is a matter of indifference sofar as the present invention is concerned, it being` for this reasonthat only such felly is illustrated. rlfhe rim 2, shown as of the plainclencher type, is directlyl mounted on such wheel body, and, as

illustrated, is generallyprovided with au integral tire retaining,"flange 3, along its one edge, namely, the edge which is disposed towardthe. body of the `vehicle, although if desired a separable, reversibleflange may be' substituted, aswill be readilv understood. n

`lt is to the other Hangs t and the locking` means provided inconnection therewith, that attention is more especially directed in thepresent connection. Such frange, as usual, in order that it may bedetachahly secured to the rim, is transversely splita; one point, as at5, in its circumference and has itsl inner edge 6 formed to seat in auencircling groove or depression 7 adjacent the corresponding` edge oftherim. Ei corresponding head 8 is of course formed on the underside of therim adjacent this edge, and at a point adjacent to the meeting ends ofthe split side-flange the bottoni wall of such groove or bead is cutaway so as to provide an elongated slot 9, through which may project twocomplementary lugs l0 and 1l, formed on the inner edges of such flangeends, respectively. These lugs, as shown in Figs. l and 2, are adaptedto project radially through such slot, and the one 'i0 thereof isundercut or recessedso as to provide a toe l2, which interloclrs, whenthe flange is in place, with the adjacentedge of the slot. llore'over,both such lugs have their opposite faces 13 and la', respectively,beveled so as to facilitate their insertion in the slot.

0f the meeting faces of the flange ends, f

the one on the end which is provided with such undercut -lug l0, isformed withr a transversely extending angular notch l5, while the faceof the other end is recessed and provided with a transverse circularhearing 16, in which is oscillatorily held a key 17. The portion of thelatter that is i'itted in such circular bearingis laterally upset so asto prevent dislodgement of the lrey while still leaving it free to beoscillated within the limits of the recess 18. The latter is of suchextent and form as to permit the lrey in one position, that shown inFig. 2, to lie wholly within the plane of the face of the correspondingflange end, while in another position, as shown in Fig. l, the

When in such last-named position Vthe aforesaid key will obviouslyprevent the removal ci the 4flange-end to 'which it is attached, theother flange-end being directly interlocked with the bottom of thegroove. Accordingly, the device in question serves to securely lock-therlang'e as a whole in its seated position on the rim. However, by simplyturning the key into the position shown. in Fig. 2, there is nothing toprevent the corresponding flange-end from being pried out oi suchgroove, and t ereupon by a slight circumferential displacement of theflange, its other end is unhooked fromengageinent with the bottom ot thegroove and the entire ange may be reinovef.

The key il", it will be observed, is securely held in its operative, orlocking position, by the engagement of the bead 2U ot the tire-shoetherewith, as shown in Fig. 3. ln other words, such key cannot be swunginto the inoperativepcsition ot Fig. 2, until the said bead has beenpushed inwardly into the position as shown in dotted outline.

@ther modes of applying the principle ct my invention may be employedinstead ot the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any ot the toilowingclaims or the equivalent of such stated means be employed. Y

l therefore particularly point ont and distinctly claim as my inventionl.
